Xbox MusicXbox Music (formerly Zune) combines Microsoft's robust catalog of over 3 million tracks with the popularity and usability of both Xbox 360 and Windows-based (phones, tablets, PCs). Xbox Music as the best of all music services: à la carte options akin to iTunes, streaming options à la Spotify, and a Smart DJ radio option similar to Pandora. As such, Xbox Music offers three ways to use the service: free, ad-supported streaming (for Windows 8 only), a $9.99 monthly subscription (dubbed Xbox Music Pass) that allows unlimited play, and the pay-per-song model via Xbox Music Store that lets you purchase and download 256kbps DRM-free MP3s (streaming music plays as 192kbps WMA files).
